Eight-Year Progression of Clinical Practice Implementation Following Guideline Training in the EGUIDE Project

Clinical practice guidelines have improved the quality and standardization of psychiatric care; however, their long-term implementation in real-world settings remains limited. The Effectiveness of the Guidelines for Dissemination and Education (EGUIDE) project was established to promote sustained evidence-based practice through a multilayered educational program for psychiatrists in Japan.

This multicenter observational study longitudinally tracked psychiatrists' self-rated clinical behavior (CB) scores related to guideline adherence for up to 8 years after initial EGUIDE participation. CB was assessed using a validated questionnaire covering general guideline use (CB-G), schizophrenia (CB-S), and major depressive disorder (CB-D), with a comprehensive index (CB-C) representing the mean of all domains. Data were analyzed using the Kruskal-Wallis test, the Mann-Whitney U test, and the Bonferroni correction (two-tailed p < 0.05).

A total of 1562 psychiatrists (mean age, 32.7 ± 7.1 years) were included. All CB indices (CB-C, CB-G, CB-S, and CB-D) significantly improved post training compared with the baseline (H = 831.2-984.0; all p < 10^-72), with small-to-moderate effect sizes (r = 0.09-0.29). These improvements were maintained throughout the 8-year follow-up, with no significant decline, and several domains showed small but continued increases between 3 and 7 years post training.

The EGUIDE program achieved long-term, sustained improvements in psychiatrists' guideline-adherent clinical behaviors through an integrated system combining education, supervision, feedback, and follow-up. This autonomous, cyclical framework represents a high-impact model for continuous quality improvement and may be adaptable to other medical specialties.
